Childhood movement skills: predictors of physical activity in Anglo American and Mexican American adolescents?

We assessed the relationship between young children's movement skills and their physical activity in early adolescence. Balance, agility, eye-hand coordination, and skinfold thicknesses in 207 Mexican American and Anglo American children (104 boys, 103 girls) were measured at ages 4, 5, and 6 years. Habitual physical activity was assessed at the age of 12 years by two interviewer-administered 7-day recalls. Ethnic differences in movement skills were not found. Young girls were better at jumping and balancing, and young boys were better at catching. Tracking of skills was low, and children's early childhood skills were not related to their physical activity 6 years later. Further studies involving additional movement skills and other populations are recommended to determine if enhanced movement skills in children promote subsequent physical activity.     

Careers Under Stress: Teacher Adaptations at a Time of Intensive Reform

There is currently a crisis of recruitment and retention of teachers in the United Kingdom. One feature of this trend is the number of teachers who are leaving the profession prematurely in reaction to the changed nature and organization of their work. This article focuses on how the crisis was experienced at the level of the individual. It explores the perceptions and interpretations of a group of teachers who left teaching or who considered leaving but remained by making adaptations to their roles; adaptations of retreatism; downshifting; and self-actualisation. The article uses data from a longitudinal study of a sample of English primary school teachers who are experiencing or have experienced occupational stress and stress-related illness. Unpredictable and stress-induced breaks in the teachers' careers are defined as `fateful moments' involving a `reassessment' and `redefinition' of each teacher's self, commitment and career. This case study of teacher stress makes emerging patterns and experiences of teacher career in the conditions of `late modernity' highly visible. The article concludes by arguing that the new and unplanned disruption in careers can involve the teachers in repeated re-inventions of the self (a stressful and convoluted process in itself) and that a reconceptualisation of teacher career is required.     

Communicating spending cuts: lessons for Australian university leaders

In 2011 and 2012, two Australian university vice chancellors flagged spending cuts at their institutions to overcome financial problems. In both cases, union and staff opposition led to public protests, intense media scrutiny, delays and retreats. This article compares the two cases to see what lessons may be drawn for university leaders faced with the complex, difficult and risky task of introducing spending cuts, a likely feature of Australian university management in the next few years. How can they do this in ways that cause minimal damage to programmes; are acceptable to those affected; and avoid undue damage to staff morale, student interests or institutional reputation?     

Effect of wall permittivity on electroviscous flow through a contraction

The electroviscous flow at low Reynolds number through a two-dimensional slit contraction with electric double-layer overlap is investigated numerically for cases where the permittivity of the wall material is significant in comparison with the permittivity of the liquid. The liquid-solid interface is assumed to have uniform surface-charge density. It is demonstrated that a finite wall permittivity has a marked effect on the distribution of ions in and around the contraction, with a significant build-up of counter-ions observed at the back-step. The development length of the flow increases substantially as the wall permittivity becomes significant, meaning that the electric double-layers require a longer distance to develop within the contraction. Consequently, there is a corresponding decrease in the hydrodynamic and electro-potential resistance caused by the contraction. The effect of wall-region width on the flow characteristics is also quantified, demonstrating that the development length increases with increasing wall-region width for widths up to 5 channel widths.
